The act of ejaculation can occur after male ligation. Male ligation surgery mainly involves ligating the male vas deferens, which is a channel for transporting sperm. After ligation, sperm produced by the testicles and epididymis will not enter the semen through the vas deferens, thus not leading to pregnancy in women. The main component of semen is prostate fluid, and ligation will not affect the ejection of prostate fluid. Therefore, ligation only blocks the transport of sperm and does not affect the production of semen in men, so there is no need to worry too much. When a man undergoes ligation, it will also cause an ejaculatory reflex during sexual intercourse, thus discharging prostatic fluid and seminal vesicle fluid into the ejaculatory duct and out of the body, but because the vas deferens has been blocked and ligated, it cannot combine with the remaining two in the ejaculatory duct. Therefore, although the act of ejaculation occurs, the semen that is discharged does not contain sperm. Vasectomy is a safer and more effective contraceptive measure. After the ligation surgery, contraception can be performed without condoms, and if a man still has a need for fertility, he can go to a regular hospital for a vasectomy.
